Systems: How AI Scales reveals how production AI handles thousands of requests, shared models, queues, state, failures, security, evaluation, cost, and continuous change. Through intuitive stories, practical architectures, and accessible mathematics, discover what it takes to transform an AI capability into a service people can trust.Volume V of The AI Systems Series.

A model can recommend an action. But what gives it permission to act—and how does it verify what happened? Agent explores tools, authority, planning, execution, recovery, security, and oversight. It begins where Reasoning ends and leads to Systems, where one successful action must become a dependable service.

A fluent answer is not necessarily a reasoned answer. Through stories, examples, visual models, and real mathematics, Reasoning reveals how AI represents problems, searches possibilities, and verifies conclusions. It begins where Context ends—and stops at one crucial boundary: a decision is not an action. That is where Agent begins.

The known surrounds us, but only some of it becomes context. The unknown is what we ask AI to resolve. How does a fluent model know what matters—to this user, from this source, at this moment? Context follows one ambiguous instruction through retrieval, RAG, memory, graphs, MCP, provenance, security, and evaluation—showing how AI drives the known to derive the unknown.

Move beyond individual prompts and engineer the full information environment an AI model receives. Learn to design, test, measure, and govern context for reliable AI workflows.
